And this is another reason you should pay attention to hot and neutral. The hot side is usually where the fuse is, as is the case in the 5061. If you swap them, you no longer have any protection against an internal hot-to-ground AC fault. Bill Ezell ---------- They said 'Windows or better' so I used Linux.

However, current US electric code is very specific about which terminal of the AC plug is wired to "hot" and which is wired to "neutral". It used to matter back in the tube days when cheap radios/TVs didn't have a power transformer. The neutral was connected to the chassis and the B+ was derived from the hot line. That gives you a hot chassis if you swap the power wires. (The chassis was all hidden in plastic, at least in theory.) What happens to a 5061 if I swap the power wires? I can imagine some second order considerations that would depend on how the power transformer is constructed.
